These are node blocks (not large equation blocks). There is a primitive test in DofMapBuilder based on number of subspaces and global dimension. The idea is to work with nodes and not dofs (multiple nodes can live a a dof). This gives a major speed-up in dof renumbering and makes the solvers run faster. It should also speed up the sparsity pattern construction and the construction of distributed dof maps. It would be good if UFC would provide some support for nodes. It's important for performance when multiple dofs live at each node.
